8 Claims. This invention relates to jewelry; and more particularly to improvements in settings or mountings for holding ornamental gems and precious stones in finger rings and rother jewelry.

Heretoiore, gem settings or mountings, especially for diamonds and the like, have been of such a structure that the major portion of the gem is concealed and the effectiveness, brilliancy, and luster of the gem are soon impaired by the accumulation of dirt. i

It is an object of this invention to provide a setting for diamonds and the like in which there are no air spaces between the reflecting surfaces oi the setting' and the diamond.

A further object is the provision of a setting having as small a hole as is practical to center the apex of the diamond, said setting having prone-s extending upwardly-from the face thereof and over the girdle of the diamond, thus enabling a maximum exposure of the underside of the stone.

A further object is the provision of a setting having the construction which enables maximum reflecting qualities from a stone, with minimum opportunities for dirt to collect.` The setting enables ready and convenient cleaning of the stone, at the same time providing a construction of maximum strength and rigidity. w

A further object of the invention is to provde a setting for a precious stone, which has the smallest aperture possible for, the apex and at the same time provides the maximum opening in the bottom of the setting.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited. in the accompanying drawing, forming part hereof, and in which:

Fig. 1 is a side elevational view of a finger ring having settings embodying my invention, the particular ring shown being adapted for use as a wedding ring. i

Fig. 2 is a plan view of one of the settings shown in Fig. 1,

Fig. 3 is a sectional view taken on line 8-3 of Fig. 2,

Fig. 4 is a side elevational view of a finger ring having settings embodying my invention,

5 is a top plan view of the setting,

Fig 6 is a bottom pian view of the setting,

Fig. '7 is a sectional view taken on line 1-1 of Fig. 5,

Fig. 8 is a side elevational view of the setting, and

' ing surfaces 2| and provided with an aperture 22 for receiving the apex of a diamond. The re- Fig. 9 is a side elevational view of a modified form oi' the setting.

Referring to the drawing, in Figs. 1, 2 and 3 there is shown a setting comprising a base IU having the upper surface thereof inclined as shown 5 at I I to provide reecting surfaces. 'I'he base is provided on its upper surface with a small aperture I2 for receiving the apex of a precious stone such as a diamond or the like. Extending up from the base I Il andisurrounding the reecting surfaces I I are arcuate prongs I3 which are bent over the girdle of a stone Il, in the usual manner, as shown in Fig. 1, to rmly hold the stone in position. The base has a conical shaped recess I5 in the bottom thereof which communicates with the aperture I2.

By means of the above structure it will be seen that a very small aperture I2 is provided in which the apex'of the diamond extends, and at the same time there is obtained a recess I5 in the underside of the base to provide the maximum opening possible to enable reflection from the underside of the stone. The inclined reflecting surfaces have the upper edges thereof encircling the aperture I2 so that when the apex of the diamond or stone is placed in the aperture I 2,' the sides of the stone will be directly in communication with the reflecting surfaces II, and thus there `will be no air spaces between the reflecting surfaces of the setting and the stone. 30

Referring to Fig. 4, there is shown a setting applied to a. ring of a, different type th'an that shown in Fig. 1. The ring in Fig. 4 is provided with a setting such as above described, and in addition there is alsov provided a large setting 35 which embodies the structure above described. The large setting shown in Fig. 4 is further illusl trated in Figs. 5 to 8, in which the setting is shown to include a base 20 having inclined reflectilecting surfaces are bordered by four upstanding prongs 23 which have the upper surfaces thereof provided with notches 24 to facilitate the upsetting of portions of the prongs over the girdle of the diamond or other stone to hold it rigidly in the setting. On the underside of the base, see Fig. 6 there is provided a conical recess 25 which communicates with the aperture 22 thus providing the maximum opening for enabling passage of light to the` stone from theunderside of the base.

As above described, the reflecting surfaces 2| communicate directly with the sidesV of the stone so that there will be no air spaces between the stone and the reflecting surfaces. g5

It is obvious that the structure above described enables the stone to be easily and conveniently cleaned as minimum opportunity is provided for the collection of dirt; at the same time the reflecting qualities of the stone are enhanced enabling the exposure of all parts of the stone and reflections from the bottom part of the stone as well as from the top. The provision of the recess in the base provides maximum strength and rigidity of the setting, providing greatest strength for the setting for the stone.

In Fig. 9 is shown a modified' form in which the inclined reflecting surfaces 2| are provided with a plurality of facets 26 which increase the reflecting qualities of the reflecting surfaces.

The foregoing disclosure is to be regarded as descriptive and iilustrative only, and not as restrictive or limitative of the invention, of which, obviously, embodiments may be considered, including many modifications without departing from the spirit and scope of the invention herein denoted and set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A gem setting, comprising a base having the upper portion thereof inclined and provided at the center thereof with an aperture to receive the apex of a stone, prongs bordering the base and extending upwardly to tightly engage the girdle of a stone, said base having a conical recess in the bottom thereof communicating with said aperture. 1

2. A gem setting, comprising a base having the upper surfaces thereof inclined and provided with a downwardly extending recess having an aperture at the center thereof, said inclined surfaces and said recess having a common upper edge, prongs bordering the inclined surfaces and extending upwardly, said prongs being provided with means at their upper ends to engage the girdle of a. stone to hold the stone firmly in the setting, said base having a recess in the bottom thereof communicating with said aperture.

.3. In a gem setting, a base having inclined upper surfaces, and provided with a downwardly extending conical recess having an aperture at the center thereof, the said inclined surfaces and the conical recess having a common upper edge so that when a stone is positioned in the recess there will be no air spaces between the inclined reflecting surfaces and the stone, and prongs projecting upwardly from the base to engage the girdle of a stone, said base having a conical recess in the bottom thereof communicating with said aperture.

4. In a gem setting, a base having inclined upper surfaces and provided With a downwardly extending conical recess having an aperture at the center thereof, the said inclined surfaces and the conical recess having a common upper edge so that when a stone is positioned in the recess there will be no air spaces between the inclined reecting surfaces and the stone, and prongs projecting upwardly from the base to engage the girdle of a stone, said base haw'ng a conical recess in the bottom thereof Acommunicating with said aperture, said inclined reflecting surfaces having facets cut therein to increase their reflecting qualities.

5. In a gem setting, a base having inclined upper surfaces and provided with a downwardly extending conical recess having an aperture at the center thereof, the said inclined surfaces and the conical recess having a common upper edge so that when a stone is positioned in the recess there will be no air spaces between the inclined reflecting surfaces and the stone, and prongs projecting upwardly from the base to engage the girdle of a stone.

6. In a gem setting, a base having inclined upper reflecting surfaces and provided at the center thereof with an aperture to receive the apex of a stone, and prongs projecting upwardly from the base to engage the girdle of a stone, there being no air spaces between said inclined reflecting surfaces land a stone mounted on the base.

'7. In a gem setting, a base having inclined upper reflecting surfaces and provided at the center thereof with means to receive the apex of a stone, and prongs projecting upwardly from the base to engage the girdle of a stone, there being no air spaces between said inclined refiecting surfaces and a stone mounted on the base.
